General problems of hydraulic hose
Industrial rubber hose has many types. Because they should be suitable for various usages. Then the inner tube should adopt various of materials for such purpose. For example, the rubber hose in chemical industry should be corrosion proof. While the rubber hose for oil transfer should have an oil resistant inner tube. Then next, let me show you some rubber hose inner tube.
First, metal
For general fluid system needs, metal inner tubes are a good choice. Their temp ratings are between -200°C to 454°C or higher. Thus metal inner tubes are an excellent choice for systems in extreme temps. Metal tubing is also a good choice when the allowable level of absorption is very low.
However, metal inner tubes are generally no longer used for highly corrosive or acidic media. Because those will corrode the metal hose after a long time. Besides, it is to note that metal hose is also less suitable for repetitive motion use. Because there will be fatigue failure.
Second, silicone rubber
Silicone hose has become the ideal material for hygienic use. Because silicone is flexible and clean. Besides, it can be medical grade and food grade. As for the temp, silicone hose can work at -53℃ to 315℃.
However, silicone has highly absorbent. Thus the industrial hoses is easy to get contamination. The medium may remain within the wall for a long time before. Steam cleaning, one of the most common methods of sterilizing silicone, may also fail to remove absorbed fluid. Besides, it can quickly damage the silicone inner tube. In addition, silicone can not work together with solvent. What’s more, high temp may cause material fail earlier. Then it makes the industrial rubber hose crack and brittle.
